'concer n: Be it known that I, PENROSE E. CHAP- MAN, a citizen of the United States, residing at thecity of St. Louis, State'of Missouri, have invented certain new and useful Improvements in Armature-Winding Machines,

- of which the following is afull, clear, and-- which the conductors may be 20.

- forming concise description, reference bei had to the accompanying drawings, forming part hereof. y

M invention relates to drum armature win "ng machines in which the wire is wound directly in slots in the surface'of the core,- and consists inthe novel. .combination and arrangements of arts as will be more fully hereinafter descri ed andclaimed.

The object of my invention is to construct an improved armature 'windi machine, by

firectly wound on the core of the armature, and in the slots 0:- openings provided for the same, without thenecessity-of doing so by hand or of first the coils and plac' them on the core a terwards usually by iand, thereby greatly expediting the operations especially in armatures havin a large number of poles, wiilerein hand win 'ng is difiicult-or impossi e,

With this object in view my invention con sists of a machine for winding drum armatures, .which comprises means for rotating the armature in a plane parallel to its shaft,

1 rneans for holding said armature tobe wound in proper relation to other portions of the" machine, means for holding'awire directi saddle 'withits'stationary and adjustable col forming guides, said saddle being ada ted to rotate with the armature, a perfora finger for the coil forming wire to said coil positionwhen released, means for formin saddle and. guides, means for throwingsai fingerback out :of the way, means for flexibly mounting said saddle, that it may follow irregularities in the movement and contour of said armature, means for automatically restoring said saddle to its normal mgagmg v and disengaging this saddlefrom the work,

A means forcontrolling rotation of the work,

means for applying a tension to the coil forming wire, means for automatically the number of'turns wound, and in the arrangement and shape of said saddle and es I v. g e

. M invention consists 1n certam detaIls, com ination, and shape of parts which will always the, case withbe more fully hereinafter described and claimed. 1

The action, operation, and construction, of my invention will be better understood by referring to the results that wouldbe obtained were one to try and wind wire or stri .diametrically upon the outside of "the flare or larger portion of a funnel, as .the wire or string would inevitably sli "towards the smaller end ofsaid funnel. t will be seen further that upon continuing to wind, the wire'or string would Be forced towards and upon the spout and accumulate thereon,

articles in lieu of a-spout' the device can readily be made to wind or deposit wire &c. u on said articles. In'my invention I utilize t action for the windingof armatures, and more especially those requiring the wire to be wound upon a chord of the circle, as is multipolar drum armatures. a j

Throughout the specifications and claims, that portion of ,the machine having the funnel characteristic is referred to as the saddle.

Having thus described the basic rinciple of my inventionin the drawings, igure 1 is a' general elevation of the machine with supporting framework removed for the sake f c e arn'ess as well as a portion of the saddle. I

removed to show ball and socket mounting onthe elastic stem, the .conical leveling -s ring also. showing. Fig. 2 is a perspective 0? thesaddle; shown immediately above andslightly removed from a 6 pole armature, partly wound, the lastcoil being shown im-' mediately below the saddle, completed, and disengaged therefrom. Similar m'arks'of sponding parts.

" Referring the drawings, 1 is the saddle carrying the stationary wire directi guides 2 of whichthere are'four one at eac corner and of which they form a part, and the auto- .matically adjustable directing and forming guides 3 each with its operating springs an reference indicate correguiding studs 5, and the manually adjustable directing guide 6 with its locking springs 7. A ball and socket joint enabling said saddle to adjust itself to irregularities is shown at 8, and 9 is a conical spring for automatically returning the saddle to its normal plane.

10 is an -elastic stem carrying the ball to which the saddle is connected, said stem being rigidly secured at its upper extremity to a supporting device, as a taper plug 11 adapted to the tail-stock of a lathe or other support, said plug having a larger opening at its lower end allowing the stem to spring but not too far.

12 is a lever adapted to disengage the saddle from the armature and permitting its rotation around the axis, said lever being connected to pedal 14 by means of connecting rod 13 and being returned to normal position by spring 12. shown at 15 and its commutator at 1'6.

17 is a perforated finger or guide through which the coil forming wire a asses to and over the saddle and its guides into the slots intended for itsreception. The tension device 18 is for applying an even tension to the wire a.

19 is a hand-wheel for convenience in operation, with the armature su orted from the same by means of the uprlg ts 20 and 21-21 being enlarged to form a counterbalance for the commutator or other unbalancing effects.

22 is a pulley for driving, with a clutch 23 contained therein, said clutch being attached to the main shaft by means of the key 24 and adapted to operate longitudinally and actuated by the edal 26 through the connecting rod 25 wit 'n the main shaft 34 and the sli collars 27.

i. he saddle 1 is proportioned to fit over the requisite section of the armature, said section representin the spout of the funnel as described herein efore. In the preferred form the saddle has its ends beveled out-' wardly from the, armature corresponding to the ta er of the funnel, the sides 9 parallel to eac other and whose edges exactly register with slots 28 in the armature .15, said beveled ends carrying the coil forming wire downwardly over the predetermined section of the armature core in a substantially similar manner to theaction of the funnel'hereinbefore described: To insure the wire bein carried fairly'into the slots-28 the bevele ends of the saddle 1 are extended at the corners to form horns 2, of which there are four, whose function is simply to guide the coil forming wire well witlnn said slots.

As it is desirable that one side of some of the coils bewound in the bottom of theslots, I have added a manually ad'ustable set of horns or guides 6 yoked toget er in the form of an inverted U having ends suitably beveled and adapted to be lowered or raised and held An armature is r in either osition by springs 7 engaging suitable notc es, said guide 6 in the lower position forcing the coil forming wire to or near to the bottom'of said slot 28, and in the u per position allowing the wire to drop in t e to of said slots co-acting with horn 2.

n order that the ends of the coils shall be of pro er shape to fit or nest one with the other haveadded the coil forming guide 3 centrally located, said guide being mounted loosely within slots cut in the ends of the saddle 1 and adapted to move perpendicularly to the plane of rotation, and studs pass through holes in the yoke of said guides 3 and through the springs 5 which are retained by said studs and press against the yoke of said guide 3, thus allowing it to move but always under tension of said springs .5. Upon the ends of guide 3. are arranged coilforming surfaces f which being parallel or nearly so tend to retain the coil-forming wire a after sliding down the beveled surface s of said guide- 3. The ends of the coil-forming surfaces are pressed by the springs 5 against t e windin reviously formed; or at the start a smal lock is placed under them so that none of the coil-forming wire may be crowded off them as it accumulates. At the completion of the coil the entire saddle, guides and all, is raised by pedal 14 provided therefor. Guides or'stops 29 are provided for compelling registry of saddle sides g with slots 28.

A iding finger 17 having holes in its tip for ti: assage of the coil forming wire 18. arranged to guide said wire directly upon the saddle at asuitable place, and said finger is flexibly mounted that it may be thrown back out of the way.

A revolution counter is shown at 30 operchain 32.

33' is one of the main bearings supporting main shaft 34.

The machine is operated as follows: The armature to be wound is secured in its carrier through supports 20 and 21, saddle 1 lowered over section desired by releasin pedal '14, stops 29 compelling registry 0 sides 9 with slot edges 28, the wire or wires a are threaded through tension devicev 18 and guiding finger 17 and to the commutator which shou d now be on the left and secured thereto or to some other fastenin when clutch 23 is actuated through ped 26 and the whole is thereby rotated to the left. The coil formin wire is thus drawn over side of saddle g and own into slot by guide 6 and dropped next down by gm surface s to fof adjust sibf 125 retaimng surface e guide-3 and retained there, and the beveled ends of the saddle carry it down to horns 2, with the same operations completed in reverse order on other end of saddle, till the revolution counter 30 indicates proper number ofturns,

ated by its shaft 31 and sprocket wheels and and away from the armature core, with sides stops for compelling said registry, and guides when clutch is released, ends of wire secured, saddle raised with pedal 14, armature rotated on its own axis to new position, and operations repeated till completely wound. However when winding the last coils it will be found that the last few slots are partially occupied with the first coils, the guide 6 is then raised to its upper limits, spring 7 re-' directing guides whose directing surfaces are placed at an angle suited to direct coil form'- lng wire within slots in said armature, means for supporting said guides in suitable relation thereto, and means for adjusting said guides relatively to said supports and said armature.
